250031-438 Unloader Valve Kits Air Compressor Inlet Valve Repair Kit

Description

Part number: 250031-438

Item name: Unloader Valve Kits/Inlet Valve Repair Kit

250031-438 unloader valve kit is specially developed for overhaul of the screw compressor inlet unloader valve. As the gateway of the compressor air intake system, the inlet unloader valve governs air intake volume. It opens for loading to suck in air and closes for unloading to cut off air intake, which realizes no-load running and protects the host during standby and shutdown.

Key Features

• Complete overhaul set for intake control mechanism, covers core moving and sealing consumables
• Designed for frequent load / unload cyclic switching of the air inlet system
• Resist oil mist erosion and repeated pressure impact from intake airflow
• Restores flexible opening & closing of inlet flap, resolves valve sticking and air blow-by
• Ensures reliable no-load operation and prevents abnormal blow-off during shutdown
